  • JPG Artifacts Help

    I have had this shot rejected for jpeg artifacts.
    Could someone tell me how to see these (before uploading)
    with the naked eye.

    Thanks,

    Mike.

    We don't actually have a "jpg artefacts" reject reason.

    If you are referring to .jpg compression then I don't see any.

    I do see some oversharpening artefacts though in the form of jaggies on the FINNAIR title, the nosegear and fin leading edge.
    If it 'ain't broken........ Don't try to mend it !

      Thanks for the reply Brian.

      In the original rejection email it stated 'Jpg compression artefacts' so
      I questioned it and asked if they could point them out for me - but the reply was 'the entire fuselage' had compression artefacts.I somehow
      cannot see anything on that scale - hence my original question here.

      Thanks again,

      Mike.

        Hello Mike, you have had quite a significant history with this issue.

        Would you like to send the original to [email protected] so we can see if it's a post-processing problem?

          Hi Anthony ,

          As requested I have sent you the original shot.

          Regards,

          Mike.

            To be honest Mike your camera is letting you down, however you should still be able to get reasonable results through post-processing.

            Firstly the original shows signs of noise and some in-camera sharpening. This means the original is already showing signs of sharpening on defined edges, such as the Finnair titles. When you then sharpen the rest of the aircraft it leads to oversharpening of the titles. You will need to use selective sharpening (see various guides on this forum for instructions).

            Be careful when resizing, I would suggest don't resize in one hit, do it in stages.

            I am not sure if you use noise reduction, if you do use it sparingly as it can often lead to a washed out appearance and a degree of compression.

            Finally, always save at the highest possible quality.

              Hi Anthony,

              Thanks for your speedy reply - I take onboard all your thoughts and
              perhaps a new camera would be a good move.

              Regards,

              Mike.
